We want to increase the volume of a fixed amount of gas from 68.2 to 153 mL while holding the pressure constant. To what temperature in degrees Celsius must we heat this gas if the initial temperature is 21.0 °C?

Using Charles's Law (V1/T1 = V2/T2), convert the initial temperature to Kelvin (21.0 °C = 294.15 K), solve for T2 in Kelvin, and convert back to Celsius. T2 = (153 mL / 68.2 mL) * 294.15 K = 660 K, which is 387 °C.
